To be fair, I've never seen GitHub's codebase. In fact, I'm not entirely sure if it's even still the same "Rails app", or if they've moved to a microservice architecture or something.

Not sure what microservice architecture has to do with it. You can have microservices that are Rails apps. :)

Yes but if you change architectures, you will have replaced much of your original codebsae.
